웹개발중인데, Markdown에서 HTML로 어떻게 변경하나요?

이렇게 적고 Submit 버튼을 누르면 DB에 잘 저장이 됩니다.

그런데 게시글을 누르면 아래처럼 나오네요 ㅠㅠ

제가 MEAN 스택으로 개발하고 있어서

이게 Schema고

var reviewSchema = new mongoose.Schema({
title: String,
    author: String,
    paper: String,
    content: String
})

이게 두번째사진 코드입니다.

<% include partials/header.ejs %>

<div class="container">
    <h1> <%= review.title%></h1>
    <h3> <%= review.author %> - <%= review.paper %></h3>
    <a role="button" class="addbutton btn btn-default btn-info" href="<%=review._id%>/edit" style="margin-left: 0px;">Edit</a>
    <form action="/reviews/<%=review._id%>?_method=DELETE" method="POST">
        <button class="addbutton btn btn-default btn-danger" style="margin-left: 0px">Delete</button>
    </form>
    <hr>

    <div class="form-group">
        <div id="wmd-preview" class="wmd-preview"> <%= review.content %> </div>
    </div>

</div>
